49ers QB Colin Kaepernick's No. 7 jersey has been "the NFL's best seller over the last three months," according to Darren Rovell of ESPN.com. Quarterbacks finished in "four of the top five slots based on sales" from April 1-June 30 on NFLShop.com. Among "just drafted rookies," Chargers LB Manti Te'o's No. 50 jersey "was the most popular" (ESPN.com, 7/20). In S.F., Ann Killion wrote Kaepernick's jersey reaching No. 1 is "a somewhat predictable result of ... spending his offseason being the most high-profile quarterback in the most high-profile sports league in the world." The "proliferation of No. 7 jerseys is just more evidence of Kaepernick's meteoric rise." However, that has some "worried about a correspondingly swift crash" (S.F. CHRONICLE, 7/21).
